5 rllenas", have invented certain new andv useful In'iprovements in Blow-Out lioots, ot which the following is a specification.

My invention relates to blow-out boots,

and has particular reference to the provision l0' of `avflap or covering` for protectingthe vario-us'fornis of fastening means employed to hold the longitudinal edges'o-f the boot in liXed relation. I

ln various forms of blow-out boots appearing on the market, the fastening means employed comprises flexible strips secured to opposite sides of the split edges of the boot and provided with 'interlocking portions or other fastening meansior tastening the edges of the boot `in fixed relation about the inner tubefbeneath the rim-cut7 or blow-out. in the outer casing. "h ianyjoit these flexible strips are secured to the edges of the boot by rowsot 'stitching or the like which permanently connect the strips to the boot. bing 'of the boot" within the casing soon chates or destroys the stitching and allows the hole in the outer casingl beneath which the bo-ot was disposed. Also'rust from the metallic rims, sand, water, or other foreign substances lenterpjthe casingand tend to destroy or materially weaken the viiabric strips and stitching and to thus allow the boot to bulge or separate. l

Further, many of the present boots are provided with tongue memberssecured to one edge of the boot and bordering upon the opening and designed, when the two edges of the boot are joined, to lie between the inner tube andlocking means to prevent the entry of dirt or other foreign substance between trie inner surface of the boot and the inner tube and `to prevent pinching of the tube at the seam or joint. In use, it is found that notwithstanding this tongue member, particles of dirt or other foreign substance work into the interior orP the boot and in a comparatively short time wear a hole in the innei tube.

The object oiithis invention is to over-. come the above disadvantages by providing a blow-out boot having aA protective flap or covering secured to the boot near the opening,

In use, the constant friction or rubn the bootto separate andblow out through which when the boot is in fixed position about the' inner "tube,` is capable of use for completely covering the fastening means which maintain the vboot intiired position. j A further objectief this invent-ion is to provide aprotective `flap for covering the fastening means and also for protecting the stitching or the like,'which secures the fas tening strips to the boot.

A further object of this invention is to Iprovide a` device of the above mentioned character which completely covers and protects the fastening `means and prevents the entry of dirt or other vforeign substances into the interior of the boot. v

A stillv further object of this invention is ,to provide a deviceot this `general character thatis simple in construction, inexpensive fl l n to `manui'acture1 convenient in .use and strongand durable. 'l

In the accompanying drawings,` forming `part of this specification and in"which like numerals are Vemployed to designate like parts throughout the several views; l is 'perspective view o ta blowout boot of any well known or preferred construction showing my protective flap overlyingl the fastening-means Fig. 2 is a plan view of one form of blow- 'outboot provided with my improved protective flap, showing the relative position oi" the flap with" respect to itsl associated parts, and r lig.l 3 is a cross sectional view of a tire casing and inner tube showing the position of the boot in actual use.

Referring to the drawings, wherein for the purpose oit illustration is shown a preterred example of my invention, the numeral 6 designates a blow-out boot composed of a plurality of laniinations of fabric or the like, such as is the common construction of these boots. Attached to the opposite edges of the boot are the locking strips 7 and 8, secured to the boot by the line or lines of stitching 9 and l0 respectively, and comprising, in the present instance, interlockingly engageable tongue and slot members l1 and l2, for securely fastening the boot in liked position about the inner tube 13 when the blow-out boot is in use within a casing 14. A strip 15 is attached to one edge of the boot at the inside thereof, and is adapted, when the two edges oi' the boot are oined, to lie between the inner tube and seam or joint,

` This protective flap 1'6 is preferably inzide ofi tough and? pliable, rubber, leether,..or textile 4febric `end hns,` one. ofiits'edges-se- `cure'dfto.the boot infproxiinity tothe fasi tenii'iglmeens employed to Aini-(iintziin .the boot i5 in ciosedjposition.: Experience liesshown` ,theft preferred vmethod-oi",securing.this protective laptothe bootl is'fto .plzicesone ,edge-,otthe seine-beneath,eitlierotthe tient d ble 'fzistening stripsfdnring tl'ieiinenufecture 20;..o-. theV boot, ,end `to utilize:- the sinne;r festeng nggineens .to securefboth protective vflgipzend t steningstrip ,to tlie body of tllezboot. .'illiis etliod l serves. to Lreduce operations end secures the l-proteotinfe flap 16I inj the proper location with respecttothe,festeningvinenns.
